The benchmark for

fl exibility

.

Whether as a single-line scanner for high-density codes, for example, in analysis

automation, with raster optics for reading trays in intra-logistics applications or

for inspecting industrial or printed products: the compact bar code readers of

the BCL 20 series convince with their high level of flexibility and handling

reliabili-ty in all areas.

The broad selection of optics also allows the scanners to be used in difficult

installation situations and in a wide range of applications, both in networks as

well as a standalone solution. Furthermore, the BCL 20 series convinces with its

outstanding reading performance through the automatic adaptation of the

receiver unit to the reading task on each scan. For an extended reading field,

such as that of a bar code reader with focusing function, the new BCL 20 S B is

availabe for higher resolution codes.

By means of simple online commands it is possible to set the reading task

without knowledge of the code. The PC-based BCL-Config tool, which is

avail-able for all Leuze bar code readers, is used to access the full function range.

Simple online commands make it possible to set the reading task without

know-ledge of codes. The BCL Config tool, which can be used for the entire function

range, is available for all bar code readers from Leuze electronic Connectivity.

Connection to industrial or Ethernet-based networks is now done directly via our

MA 200i modular interfacing units.

integration –

Various optics models: Different models with front or lateral beam exit

ena-ble optimum use of the installation space. Depending on the code alignment,

single-line or raster scanners offer optimised reading capacity

High, constant scanning rate up to 1000 scans/s: Considerable increase in

the reading reliability through multiple decoding of the read codes, even during

fast processes

Large depth of field and wide opening angle: High reading capacity with codes

having line thicknesses as narrow as 150 μm facilitates front or lateral reading

on your goods

Integrated multiNet: Up to 31 scanners can be networked in Leuze electronic's

own scanner network with minimal installation effort and, if desired, integrated

via gateways to the fieldbus level or directly to the host

Simple operation: With the aid of online commands such as AutoConfig, the

scanner can be set optimally, even without knowledge of the code

Easy configuration: The PC-based BCL-Config operating software for all Leuze

bar code readers simplifies adjustments and direct communication with the

scanner through graphical configuration

Blue laser diodes with extended reading field without focus adjustment for

higher resolution codes and optimized optics for glossy and cylindrical objects.
